The thrill-seeker who could have surfed a world record 100ft wave said he felt "overwhelmed" by his extraordinary feat.

Garrett McNamara told surfertoday.com: "I feel very blessed and I feel that we've achieved everything we wanted to do with Portugal and Nazare, especially. We've been planning this for a while and it feels really amazing to share with everybody."

"Personally, it was very challenging. You just have to stay in the moment, stay focused on what you're doing. We're really comfortable here, but some of those waves. We were surfing in zones we haven't surfed, so it was a little overwhelming."

The surfer could break his own world record that stands at 78ft, which he also rode in Nazare at the end of 2011.
